The constituents of my invention are gum of catechu common salt, saltpeter, and ground flaxseed.

To prepare a sufficient quantity of my compound to loosen and remove the incrustation I from a ten-horsepower boiler, I take one-half of one pound of gumwcatechu, three pounds of salt, one-half of one pound of saltpeter, and one pound of ground flaxseed, and pulverize finely, and thoroughly mix all together into a uniform mass, when the mixture is ready for use; or, if preferred, to apply the mixture in a fluid form; a sufficient quantity of water may be added to effect the desired change.

The proportions above specified need not be strictly adhered to, as the same may be varied and the same results be still attained from its use. larger quantity of the compound should be used.

I apply said compound in the following manner: The mixture may be thrown into the boiler at any time when the steam is not on,
